[Hepatitis B virus infection status and clinical characteristics in patients with rheumatoid arthritis]

Objective: To investigate the epidemiology of hepatitis B virus (HBV) infection in patients with rheumatoid arthritis (RA) in China and its association with RA disease characteristics. Methods: A cross-sectional study. A retrospective study was conducted on RA patients recruited from January 2001 to February 2023 in the Department of Rheumatology and Immunology, Sun Yat-Sen Memorial Hospital. Demographic and clinical data were collected including age, gender, disease duration, active smoking, RA disease activity, physical function, radiographic assessment, serological markers of HBV infection and liver function indicators. According to the status of HBV infection, RA patients were grouped as chronic HBV infection, resolved HBV infection and no HBV infection groups. The distribution of each group and the clinical characteristics of RA patients were analyzed. Results: Among 1 941 RA patients, 1 461 (75.3%) completed HBV screening, including 335 males (22.9%) and 1 126 females (77.1%), with a mean age of (55.4±13.1) years. The prevalence of chronic HBV infection was 10.1%(148/1 461), which was significantly higher in male patients than in females [14.6%(49/335) vs 8.8%(99/1 126), P<0.001], especially among those males born from 1970 to 1979[20.0%(7/35) vs 8.5%(17/201), P=0.037] and 1980-1989 [31.8%(7/22) vs 10.5%(14/133), P=0.007]. Among 148 RA patients with chronic HBV infection, there were 5 cases (3.4%) of chronic hepatitis B, 2 cases (1.4%) of HBV-associated cirrhosis and 1 case (0.7%) of hepatocellular carcinoma. The prevalence of resolved HBV infection was 57.6%(841/1 461). There were 472(32.3%) patients with no HBV infection and 267(56.6%) of them showed negative anti-HBs. Among all RA patients, 15 (1.0%) patients had abnormal liver function, of which 7 cases were drug-induced liver injury, 5 cases were chronic hepatitis B, 2 cases were non-alcoholic fatty liver disease, and 1 case was primary biliary cholangitis. Conclusion: Chronic HBV infection remains a common complication in RA patients in China, the infection rate is 10.1%, and the screening and management of HBV infection should be strengthened in clinical practice.

[Clinicopathological features and diagnosis of pericytic tumors of the kidney]

Objective: To investigate the clinicopathologic features,diagnosis and prognosis of pericytic tumor of the kidney. Methods: Three cases of pericytic tumor of the kidney (two cases were diagnosed as glomangiomyomas and one case as pericytic tumor,unclassified) were collected from the affiliated Hospital of Qingdao University between January 2014 to May 2021; the clinical and morphologic features, immunohistochemical and molecular characteristics were analyzed and the relevant literature was reviewed. Results: The three patients included one male and two females, with ages ranging from 21 to 70 years. In two patients the tumors were detected incidentally at physical examination and one patient presented with low back discomfort. Imaging showed a rounded nodular soft tissue density shadow in renal parenchyma, and enhancement scan showed uneven delayed enhancement. Grossly, two tumors were located in the renal hilum and one in the renal parenchyma; all were nodular. The tumors were measured in size from 1.6 cm to 5.1 cm (mean 4.1 cm) and showed gray or gray-red cut surface. Histologic examination showed the tumor cells were arranged in solid sheets or small nodules, closely related to vascular wall. Tumor cells were mostly epithelial-like with abundant cytoplasm, light eosinophilia, obscure boundary and round nuclei with visible nucleoli. Vague bundles and fascicular arrangements of smooth muscle component were noted in some areas, with transition of both components. There was no necrosis. By immunohistochemistry, the tumor cells strongly and diffusely expressed vimentin, SMA and collagen Ⅳ, two cases expressed CD34, all three cases expressed PDGFRB to varying extent, and the Ki-67 index was 2%-3%. PCR tests showed absent K-RAS, BRAF V600E gene mutation in all three cases. PDGFRB mutations in exons 3 and 18, respectively were found in two of the three cases by high-throughput sequencing, and no NOTCH 1/2/3 gene fusions were found in any of them. Follow-up information (range: 6-92 months) showed no evidence of local recurrence or distant metastasis in all three patients. Conclusions: Pericytic tumor of the kidney is a rare mesenchymal tumor originating in the kidney with differentiation to smooth muscle, most commonly glomus tumor. The mild pleomorphism, close relationship with vascular wall and spindled smooth muscle components suggest the diagnosis of the tumor. Expression of both epithelial and muscle-associated markers aids the diagnosis. PDGFRB gene mutations may have an important role in the development of this tumor. Most patients have a good prognosis, and a few cases have malignant biological behavior.

[Oncocytic papillary renal cell carcinoma: a clinicopathological analysis of nineteen cases]

Objective: To investigate the clinicopathological characteristics, immunophenotype, and molecular signatures of oncocytic papillary renal cell carcinoma (OPRCC), and to compare these findings with those in type 1 papillary renal cell carcinoma (PRCC 1). Methods: The clinicopathologic data of 19 patients with OPRCC from the Affiliated Hospital of Qingdao University (16 patients) and the 971 Hospital of People's Liberation Army Navy (3 patients) from October 2003 to February 2021 were collected. Histologic, immunohistochemical (IHC) and molecular analyses, together with a control group of 15 cases of PRCC I diagnosed in the same period, were assessed. Results: The cohort included 15 males and 4 females, with a median age of 61 years (range, 47-78 years). In 13 patients the tumors were found at physical examination; four presented with painless gross hematuria and two with low back pain. As for the pathologic stage, 14 patients were pT1, one patient was pT2a, three patients were pT3a and one patient was pT4. The tumor size ranged from 1.7-14.0 cm, with clear boundary and soft texture. The cut surface was grayish-yellow and grayish-red. Microscopically, the tumor cells were mainly arranged in papillary (10%-100%) and acinar (tubular) patterns, with strongly eosinophilic cytoplasm, round or irregular nuclei, and prominent nucleoli (WHO/ISUP grade Ⅲ). Two cases showed sarcomatoid differentiation. Stromal foamy macrophages were visible in all cases. IHC staining showed diffuse strong positivity for AMACR in all cases. RCC (18/19), CD10 (17/19), vimentin (16/19) and PAX8 (17/19) were positive in most tumors. CK7 was expressed in about 50% of cases. Fluorescence in situ hybridization identified trisomy 7 in eight patients, trisomy 17 in seven patients, and the two aberrations occurred simultaneously in seven cases. Eight of 13 men had Y chromosome deletion. All patients were followed up for 8-120 months. Three patients died of metastases at 8, 62 and 82 months postoperatively, respectively, and one patient relapsed 36 months after surgery. Compared with PRCC1, OPRCC tended to have higher nuclear grade, and stromal foam cell aggregation was more commonly found (P<0.05). The expression of CD10 and EMA were different (P<0.01). There was no significant difference in the survival rate between the two groups (P=0.239). Conclusions: OPRCC has unique morphologic features, and its immunophenotype overlaps but differs from PRCC1. The molecular results support that it belongs to a morphologic variation of PRCC. This tumor has similar biologic behavior to PRCC1, and has a poor prognosis when sarcomatoid differentiation occurs.

AB0276 COMPARISON OF METABOLIC DYSFUNCTION-ASSOCIATED FATTY LIVER DISEASE WITH NON-ALCOHOLIC FATTY LIVER DISEASE IN IDENTIFYING CARDIOVASCULAR RISK IN CHINESE INDIVIDUALS WITH RHEUMATOID ARTHRITIS

Background

The nomenclature from non-alcoholic fatty liver disease (NAFLD) to metabolic dysfunction-associated fatty liver disease (MAFLD) is considered to identify more cardiovascular disease (CVD) risk in general population, and patients with rheumatoid arthritis (RA) carry an excess risk for CVD.

Objectives

To compare MAFLD with NAFLD in identifying CVD risk in RA patients.

Methods

Clinical data from a Chinese RA cohort were retrospectively analyzed. Hepatic steatosis was defined by abdominal ultrasound examination. CVD risk in RA patients was estimated by the Prediction for Atherosclerotic Cardiovascular Disease Risk in China.

Results

Among 513 included RA patients, 78.4% were female and the mean ± SD age was 51.8 ± 12.6 years. The prevalence of MAFLD and NAFLD was 21.4% and 20.5%, respectively. 10.9% RA patients concomitated with CVD events and 32.4% had a high 10-year CVD risk. Multivariate logistic regression analysis showed that both MAFLD and NAFLD were associated with an increase in CVD events (MAFLD: AOR = 2.303 [95% CI 1.197, 4.429]; NAFLD: AOR = 2.478 [95% CI 1.185, 4.779] and high 10-year CVD risk (MAFLD: AOR = 3.184 [95% CI 1.777, 5.705]; NAFLD: AOR = 2.870 [95% CI 1.597, 5.156]; all p < 0.05). The NRI and IDI was -0.011 (95% CI -0.025, 0.003) and -0.002 (95% CI -0.007, 0.002) for CVD events, and 0.012 (95% CI -0.014, 0.038) and 0.005 (95% CI -0.003, 0.013; all p > 0.05) for high 10-year CVD risk, which indicated no additional CVD events and high 10-years CVD risk were identified when replacing NAFLD with MAFLD in RA patients.

Conclusion

Both MAFLD and NAFLD are associated with an increased CVD risk which implies the importance of early detection and management of MAFLD or NAFLD in RA patients. However, new nomenclature of MAFLD identify no additional CVD risk in RA patients.

[The characteristics of non-alcoholic fatty liver disease and its associated factors in patients with rheumatoid arthritis]

Objective: To investigate the characteristics of non-alcoholic fatty liver disease (NAFLD) and its associated factors in rheumatoid arthritis (RA) patients. Methods: This cross-sectional study recruited 385 RA patients [including 72 (18.7%) male and 313 (81.3%) female] who received abdominal sonographic examination from August 2015 to May 2021 at Department of Rheumatology, Sun Yat-Sen Memorial Hospital. There were 28 RA patients at 16-29 years old and 32, 80, 121, 99, 25 at 30-39, 40-49, 50-59, 60-69, ≥ 70 years old, respectively. Demographic and clinical data were collected including age, gender, history of alcohol consumption, disease duration, body mass index (BMI), waist circumference, blood pressure, RA disease activity indicators and previous medications. Logistic regression analyses were used to identify the associated factors of NAFLD in RA patients. Results: The prevalence of NAFLD was 24.2% (93/385) in RA patients, 26.3% (21/80) in 40-49 age group and 33.1% (40/121) in 50-59 age group. There were 22.1% (85/385) and 3.6% (14/385) RA patients with overweight and obese, in which the prevalence of NAFLD was 45.9% (39/85) and 78.6% (11/14) respectively, which was 2.6 folds and 4.5 folds that of RA patients with normal BMI. Although there was no significant difference of age, gender and RA disease activity indicators between RA patients with or without NAFLD, those with NAFLD had higher proportions of metabolic diseases including obese (11.8% vs. 1.0%), central obesity (47.3% vs. 16.8%), hypertension (45.2% vs. 29.8%) and type 2 diabetes mellitus (24.7% vs. 12.0%), consistent with higher levels of total cholesterol [(5.33±1.31) mmol/L vs. (4.73±1.12) mmol/L], triglyceride [(1.51±1.08) mmol/L vs. (0.98±0.54) mmol/L] and low-density lipoprotein cholesterol [(3.37±0.97) mmol/L vs. (2.97±0.78) mmol/L, all P<0.05]. Multivariate logistic regression analysis showed that BMI (OR=1.314) and triglyceride (OR=1.809) were the independent factors positively associated with NAFLD in RA patients. Conclusion: NAFLD is a common comorbidity in RA patients, especially in those with middle-aged, overweight or obese, which is associated with high BMI or high triglyceride. Screening and management of NAFLD in RA patients especially those with overweight, obese or dyslipidemia should be emphasized.

[The characteristics and associated factors of functional limitation in patients with rheumatoid arthritis]

Objective: To investigate the characteristics of functional limitation and associated factors in patients with rheumatoid arthritis (RA). Methods: Consecutive patients with RA were recruited from August 2015 to June 2019 at Department of Rheumatology, Sun Yat-Sen Memorial Hospital. Demographic and clinical characteristics including age, gender, erythrocyte sedimentation rate (ESR), visual analogue scale (VAS) of pain, clinical disease activity index (CDAI), modified total Sharp score were collected. Physical function was assessed by the Stanford health assessment questionnaire disability index (HAQ-DI).Ordered logistic regression was used to analyze the related factors of HAQ-DI. Results: A total of 643 RA patients were finally recruited including 114 males and 529 females with mean age (49.7±12.9) years. There were 399 (62.1%) patients having different degrees of functional limitation, who were classified as mild (293, 45.6%), moderate (73, 11.4%) and severe (33, 5.1%). The prevalence of functional limitation was positively correlated with age and disease activity. The most restricted activity was walking [43.5% (280/643)], followed by gripping [36.1% (232/643)], reaching [35.5% (228/643)], daily activities [33.4% (215/643)], hygiene [33.0% (212/643)], dressing and grooming [29.7% (191/643)] and arising [29.1% (187/643)], and the last eating [18.4% (118/643)]. Multivariate ordered logistic regression analysis showed that age (OR=1.019, 95%CI 1.004-1.035),pain VAS (OR=1.820, 95%CI 1.616-2.050), ESR (OR=1.009, 95%CI 1.001-1.017), CDAI (OR=1.080, 95%CI 1.059-1.102) and modified total Sharp score (OR=1.010, 95%CI 1.004-1.015) were associated factors of functional limitation. Conclusion: The majority RA patients have functional limitation. Age, pain and active disease are independent associated factors. Therefore, target treatment and control of pain should be emphasized in RA patients.

AB0883-HPR CHRONIC RHEUMATIC DISEASE MANAGEMENT AND THE SELF-EFFICACY OF RHEUMATOID ARTHRITIS

Background:

Rheumatoid arthritis (RA) is a common chronic disabling autoimmune disease, which cannot be cured completely at present, and patients need long-term medication treatment. The overall management of RA disease and patient self-management is important. Therefore, we built up a chronic rheumatic disease management team, formed by rheumatoid clinicians, clinical nurses and case managers, to provide “integrity continuity” disease management for RA by hospital on-site and WeChat APP. To this end, we used the arthritis self-efficacy scale-8 (ASES-8) to investigate the effect of the chronic disease management with RA.

Objectives:

To explore the effect of chronic rheumatic disease management and the related factors of self-efficacy of RA patients.

Methods:

Consecutive outpatients with RA who had been implemented chronic disease management were recruited from January 2019 to January 2020. A questionnaire survey of ASES-8 and clinical data were collected.

Results:

1. Among the 376 RA patients who have completed the survey, mean follow-up time of chronic disease management was 29 (8, 41) months, 35.4% patients in CDAI remission stage of disease activity, median ASES-8 score was 59(47,70), and 61.2% patients had medium or above medication adherence.

2. Patients with low ASES-8 had higher RA disease activity (including TJC28, SJC28, Pain VAS, PtGA, PrGA, ESR, CRP), more patients with dysfunction and lower medication adherence than those with high ASES-8 (all P<0.05).

3. Patients were divided into CDAI active RA group and in remission group, and those with low ASES-8 in remission group participated in chronic disease management for fewer months than those with high ASES-8 (median 20 vs. 32, P=0.033), and the HAQ-DI score was higher (P < 0.05). Active RA patients with low ASES-8 had higher disease activity, higher HAQ-DI (median 0.25 vs.0), fewer times of participating in patients’ exchange meeting (median 0 vs.1), lower medication adherence (10.8% vs. 25.9%), and more anxiety or depression (57.6% vs. 31.8%) than those with high ASES-8 (all P < 0.05, Table 1 below).

Conclusion:

The rheumatic chronic disease management team can help RA patients achieve a higher remission rate by continuous chronic disease management through hospital on-site and the Internet, and can help patients with good self-efficacy and medication adherence. In addition to disease control, we should pay attention to functional limitations and problems of back to work with RA patients in remission, while should pay attention to activity participation, medication adherence and emotional problems with active RA in further practice.

POS0539 PAIN IS AN INDEPENDENT ASSOCIATED FACTOR ON FUNCTIONAL LIMITATION IN CHINESE PATIENTS WITH EARLY RHEUMATOID ARTHRITIS

Background:

Rheumatoid arthritis (RA) is a leading cause of extremity disability in Chinese female population according to 2006 national survey. However, less epidemiological data about functional limitation in Chinese RA patients have been published.

Objectives:

To investigate the prevalence, characteristics and associated factors of functional limitation in Chinese RA patients.

Methods:

Consecutive patients with RA were recruited. The demographic and clinical data were collected including indicators of disease activity, functional assessment and radiographic assessment. According to Health Assessment Questionnaire Disease Index (HAQ-DI), functional limitation was defined as: mild (0 < HAQ-DI ≤ 1), moderate (1 < HAQ-DI ≤ 2), and severe (2 < HAQ-DI ≤ 3).

Results:

There were 643 RA patients recruited with 82.3% female and mean age 49.7 ± 12.9 years. The median (IQR) of total HAQ-DI was 0.25 (0.00-0.75) and there were 399 (62.1%) RA patients with functional limitation including 293 (45.6%), 73 (11.4%), 33 (5.1%) with mild, moderate, and severe functional limitation, respectively. The highest prevalence of functional limitation subdimension was ‘‘walking’’ (43.5%), followed by “grip” (36.1%), ‘‘reach’’ (35.5%), ‘‘common daily activities’’ (33.4%), ‘‘hygiene’’ (33.0%), ‘‘dressing and grooming’’ (29.7%), ‘‘arising’’ (29.1%), while the lowest was ‘‘eating’’ (18.4%). Further age stratification showed that the prevalence of functional limitation was increased with age (P < 0.001), but no difference between male and female RA patients (58.8% vs. 62.8%, P = 0.426). The prevalence of functional limitation of RA patients with disease duration < 1 years (early), 1-10 years (intermediate) and ≥ 10 years (long) were 70.2%, 55.9% and 74.5% respectively, showing a U-shaped curve (Figure 1A), which indicated that early RA also had high rate of functional limitation. Furthermore, early RA patients had the highest proportion of severe functional limitation (14.3% vs. 2.0% vs. 8.7%, Figure 1B), together with higher prevalence of functional limitation of all eight subdimension than those with intermediate disease duration (P < 0.05, Figure 1C). There were significant differences in Pain VAS, indicators of disease activity, functional and radiographic assessment among RA patients with different disease duration. Compared with those with intermediate disease duration, early RA patients had higher Pain VAS, higher disease activity indicator (including ESR, CRP, CDAI), higher HAQ-DI, but lower radiographic indicators (all P < 0.05). There was no significant difference in disease activity and functional indicators between early RA patients and those with long disease duration. Multivariate ordered logistic regression analysis showed that Pain VAS (OR = 2.116, 95% CI: 1.483-3.019), disease activity indicators [including CRP (OR = 1.047, 95% CI: 1.011-1.084) and CDAI (OR = 1.128, 95% CI: 1.054-1.208)] were associated factors of functional limitation in early RA patients.

(B) The different degrees of functional limitation in different disease duration groups of RA patients. (C) The subdimension characteristics of functional limitation in different disease duration groups of RA patients.

Conclusion:

Near two third early RA patients have functional limitation, in which both pain and active disease are independent associated factors. Management of pain and target treatment in early RA patients should be emphasized.

POS0534 THE PREVALENCE OF HYPERTENSION AND ITS POTENTIAL ASSOCIATED FACTORS IN CHINESE PATIENTS WITH RHEUMATOID ARTHRITIS

Background:

Cardiovascular disease (CVD) is the leading cause of mortality in patients with rheumatoid arthritis (RA), and hypertension is a modifiable risk-factor for CVD. In addition, comorbidities may shorten the life span of RA patients, which appears to be the consequence of an increased prevalence of CVD. RA patients with comorbidities might not be given the equal treatment in daily practice compared with patients without comorbidities.

Objectives:

To investigate the prevalence of hypertension and its associated factors in Chinese RA patients.

Methods:

Consecutive patients with RA were recruited from August 2015 to September 2019 at Department of Rheumatology, Sun Yat-sen Memorial Hospital. Demographic and clinical characteristics were collected including indicators of disease activity, functional assessment and radiographic assessment and CV-related comorbidities.

Results:

There were 674 RA patients recruited with 82.3% female and mean age 49.9±13.0 years. The prevalence rate of hypertension in RA patients was 32.9%, followed by dyslipidemia (9.9%), type 2 diabetes (8.8%), hyperuricemia (8.5%), fatty liver disease (8.0%), CVD (6.2%) and chronic kidney disease (3.3%). The prevalence of hypertension was 38.7% and 31.7% in male and female RA patients respectively (P = 0.144). Further age stratification showed no hypertension in RA patients at 16-19 years, 2.0% at 20-29 years and 8.1% at 30-39 years. The prevalence of hypertension greatly increased after 40 years old with 24.5%, 38.6%, 54.9%, and 63.6% in RA patients of 40-49, 50-59, 60-69, ≥ 70 years old respectively, and there was no significant difference between male and female RA patients of different age (Figure 1). Compared with those without hypertension, RA patients with hypertension had advanced age (57.3 ± 9.3 years vs. 46.3 ± 13.0 years), long-standing disease duration (median 60 months vs. 48 months), higher disease activity indicators [including PtGA (median 4 vs. 3), PrGA (median 3 vs. 3) and ESR (median 33 mm/h vs. 27 mm/h)], higher functional indicator [HAQ-DI (median 0.25 vs. 0.13)], worse joint destruction [JE subscore (median 10 vs. 6)] and higher proportions of comorbidities [including type 2 diabetes (14.9% vs. 5.8%), hyperuricemia (13.1% vs. 6.1%), chronic kidney disease (6.3% vs. 1.8%), dyslipidemia (15.8% vs. 7.1%), CVD (10.4% vs. 4.2%) and fatty liver disease (13.5% vs. 5.3%), all P < 0.005]. Multivariate logistic regression analysis showed that comorbidities including hyperuricemia (OR = 1.977, 95% CI: 1.002-3.900), dyslipidemia (OR = 1.903, 95% CI: 1.102-3.288) and fatty liver disease (OR = 2.335, 95% CI: 1.278-4.265) were associated factors of hypertension after adjustment for age and gender

Figure 1.

The prevalence of hypertension in different age and sex groups of RA patients.

Conclusion:

Hypertension is the most common CV-related comorbidity in Chinese RA patients which is associated with hyperuricemia, dyslipidemia and fatty liver disease. Detection and management of hypertension and other CV-related comorbidities in RA patients should be emphasized.
